yLVICHINE F-OR 'MAKING' AND WRAPPING- WEBBING' BOUT-STRAPS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.

Be it known that I, JOHN W. RICHADSON, of South Braintree, in the county of Norfolk, and State of Massachusetts, have invented a Machine for Making-.and Wrapping VVebbing Boot-Straps; and I do hereby declare that the following, taken in connection with the drawings, which 'accompany andform part of this specification, is a description of my invention suicient to enable those skilled in the art to `practise it.

ln the manufacture of webbing boot-straps, it is customary to envelop or wrap the whole or a large part ofthe webbing-strap in softpaper, to prevent the strap from becoming soiled, either'by the maker of the bootin stitching the strap to the vboot-leg, or by a perv son or persons trying ou theboot. A

My invention relates to' the manufacture of such \boot-straps, with particular reference to the employment Vof mechanism for automatically feeding the webbing and vthe enveloping-paper, cutting olf the webbing and the paper, each to the respective length required for, each strap, doubling or folding the opposite edges of the paper down npon the webbing, and folding the strap and cementing its opposite ends together.

My invention consists primarily in thus automatically preparing wrapped boot-straps. l v

The drawing represents a machine embodying my invention,

A shows the machine in plan. B is a side elevation of it.

G, a vertical longitudinal and central sect-ion of it.

c denotes a frame-work, having a series of bear- Aings for supporting the shaft-s or journals of the various rolls.

-x denotes the strip of webbing, and y the stlip of enveloping-paper. These strips are taken respectively from webbing and paper rolls, around which they` are wound in continuous lengths, placed-in any convenient location beyond the machine.

The strip-of paper,l 'which is wider than the webbing, enters the machine between two feed-'rolls b o, -and passes from the rolls over a bed, d, over which is avertically-reciprocating cutter, e, whiph, receiving a downward movement at proper time, evers from the strip a piece, of a length tol form the envelope or wrapper for the strap.

l The lower feed-roll b has a positive intermittent ro-A tative movement imparted to it, and the upper: roll c is a lpresser-roll, kept down against the lower roll, l'or against the paper passing between the rolls, by suitable springs.

The roll b has its movement imparted to it by any.

suitable mechanism, that which I prefer being as follows:

Upon one end of the roll-shaft is a-grooved pulley, j, banded to a pulley, g, on the shaft of a feed-roll, h, said shaft carrying a gear, @'meshing -into and driven Iby an intermediate, lc, driven by a gear, l, on a driving-shaft, m. The teeth ot' the gearl extend only partially around the wheel n.

When the teeth are in connection, motion is im- Y parted to the rolls b c, andthe paper is fed.-

The end'of the paper passes over a plate, o, and

its opposite edges under two lips or flanges p p, vturned over at the opposite edges of theplate. These lips, and the 'parts of the plate beneath them, are graditlly bent over, as seen at A, so that as the paper progresses between them, itsedges are folded over. A y

After alengthof paper to forni a wrapper has been fed through the rolls, the teeth of the gear l pass by the gear It, and the rotation of the rolls ceases. The

cutter e then descends' and sever-s the wrapper orwrapper-blank, the cutters movement being imparted as follows: l

On the end of the driving-shalt, opposite the gear I, is a grooved pulley, j, bandedv to a pulley, q, on a cam-shaft, '1'. This shaft lr carries at each end a caniwheel, s, upon whose periphery one end of a lever, t, d

is pressed by a spring, u, the opposite ends of the two levers being jointed to the lower ends of two links 1:,

whose upper ends are jointed to the opposite ends ot' the cutter-stock. V-K

'Just after the feed-rolls I) c lstop moving the papel', the cams lift the ends ofthe levers resting upon them,

thereby drawing down the cut-ter and severing the' under two i'iction or presser-rolls u z', which, press-r ing the cloth down to the paper, cause cloth and paper to move together.

The cloth passes under the folding-edges of the plate, asseen at A, the throat of the plate correspond-A ing in width to the webbing, and the opposite edges of the paper being folded over the opposite edges of the. webbing, as the webbing and paper are fed over and through the plate.

yThe webbing strip is fed or drawn along by two feed-rolls a h, the lower one of which, h, is mounted on the shaft carrying the gear c', driven by the intermediate k and gear l, as ,before set forth.

The `upper roll a? is a presserroll, being pleised down byl suitable springs, but its Ashaft carries a gear, b2, driven by the Vgear i.

The webbing rolls h c? are intermittently driven by the gearing, as are the paper rolls -b c. They draw thel strip of webbing along until the wrapping-,end of the paper reaches them, and thenthey draw both papel' and webbing as one.

In front of the feed-rolls h. a2 is a vertically-reciprocating cutter, c", that severs the wrapped strip of webbing.

' The opposite ends of the cutter-stock are connected by links d2 to the rear ends of rocker-levers e2, whose opposite ends rest upon, and are actuated by camwheels f2 on the driving-shaft, the cams forcing such ends ofthe levers upward, and thereby depressing the cutter, and springs if carrying the ends of the levers down, when the cam-points havepassed them, thereby raising the cutter.

The wrappingof the webbingleaves a strip of webbing ext-ending beyond each end of the wrapper, as

, seen at D.l (The webbing may be wrapped, however,

the whole length ofthe strap.)

vWhen the cutter descends to cnt the webbing, a piece ofwebbing of the length required for the strap has passed by the cutting-plane, and rests upon aft-able, h", its outer cud upon the front end of this table. While the webbing thus lies upon the table, and, preferably, before the strap is severed, cement is applied to the upper surface ot' the outer end of the webbing as follows:

A paste-brush is placed upon a rod, i, projecting from the end of a rocker-arm, k2, turning on a pin, l, and connected by a link, m2, with a crank-piu on a wheel, n2, at the end cfa shaft, '02, carrying a gear, p2, mesfhing into and driven by a gear, q2, on the drivingsha t.

W henthe arm L2 is thrown out, the bristles of the" paste-brush enter a cement-containing trough and `take upthe paste, and when the arm goes up, the

. pass fi'eely down through it, folded over a tongue, fr.

ylhis tongue 'r isiixedi to the bottomof a slide, s, that travels vertically between ways or guides, t2.

lhe slide is forced up by a spring, uz, and is moved down by an armfv2, fixed upon a shaft, wz, which carries at its outer endan arm, x2, jointed by a link ,toa

locker-arm, y", which is actuatedby a cam, z", on thedriving-shaft.

fixen the cam presses down the arm y2, the slide lhe :tongueearriesthe fold in the strap down through the slit between a roll, a3, on the shaft o2, and a roll, b, on the driving-shaft, whichl rolls bite upon the folded strap, and feed it between them, and when the 4two ends of the vstrap are brought together between the rolls, the cement-applied end is pressed against the other end, thus fastening the two together.

Thus finished, the straps are readyto be packed, and each is ready for application to a boot-leg.

By this method of preparing straps, it will be ohvious that they can be rapidly and uniformly made, at a comparatively small cost'of production, and without handling the webbing, as is necessary when the straps are made up by hand.

It will be obvious that the details of construction and arrangement of my'mechanism for wrapping and otherwise prepaxing webbing straps may be modified without departing from vmy invention, the essential feature being in so combining and arranging mechanism, that webbing Ato form the straps, and paper to Wrap them, are automatically cut into proper lengths, and the strap automatically covered by the paper, as

. well as in the combination, with such cutting and wrapping-mechanism, of the mechanism4 foi' applying the cement and folding the strap.

I claiml The combination of mechanism forv feeding the paper with.l mechanism for feeding the webbing and wrapping it with ,the paper, substantially as described.

Also, in combination with the feeding and wrap-5 ping-mechanism, the mechanism for cutting the paper and the mechanism for cutting the webbing, substantially as described. ,t

Also, in combination with the mechanism forfeeding, cutting, and wrapping the webbing, mechanism for folding the strap, substantially as described.

Also, in combination with the mechanism for feeding, cutting, and wrapping the webbing, mechanism for applying cement to the ends of the strap, substantially as described.

Also, the details of construction and. arrangement of the feed-rolls l) c, a?. 71, and a b, the paper-folding plate o, the mechanism for working the paste-brush, and the folding-tongue fr and mechanism for working it, substantially as described. i
